HOOD FOB AUTOEEQBILES.

Application filed. @ctober 1?, 1917.

motors of automobiles, motor trucks and the like, and particularly relates to a ventilating motor hood.

The prime object of the invention is to provide a hood with a main ventilating opening and an auxiliary opening, rearward of the main opening, the openings being formed in each SldBGf the hood or at least-in that side at which the manifold is located, together with shutters controlling the respective openings and so arranged that airmay be directed between the for- Ward shutters against the manifold and exhausted through the shutters at the exhaust opening, the respective shutters being adapted to be disposed in various angular positions to completely close the hood at the openings as in extreme cold Weather for example, or to deflect rain or snow While permitting an appreciable degree of ventilation, the shutters being furthermore adapted to be positioned to constituteboth openings air inlets whereby the air will be directed not only against the manifold and adjacent parts to be primarily cooled but also rear- Wardly through the hood to carry oil the radiated heat from the exhaust pipe and other parts beneath the footboard, whereby to promote the comfort of the driver.

A more specific object of the invention is to provide operating and controlling means for the shutters constructed and arranged to facilitate the adjustment of the shutters to suit the various conditions and adapted to retain the shutters in a given adjustment.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar reference charactors indicate coresponding parts in all the Specification of Zetters Patent.

Fig. 3 is a fragmentary view showing a portion of the elements of Fig. 2 in difierent adjustment;

Fig. 4c is a detail in transverse vertical section on the line 4--4, Fig. 1;

Fl 5 is a detail in horizontal section on the line 5-5, Fig. 1.

In carrying out my invention in practice, the hood 10 may in general be of any approved form. in the hood Iproduce at a side or both sides thereof, an opening 11,

and rearward thereof a second smaller opening 12. In the opening 11 a series of vertically disposed shutters 13 are provided and similarly in the opening 12 a series of vertical shutters 14 are provided.

The respective shutters are so pivoted at the top and bottomas to turn on verticalaxes for disposing the shutters in various angular positions. In Fig. 2 the full lines show the forward shutters 13 so disposed as to deflect an air current between the shutters through the opening 11 to the interior of the hood While the rear shutters 12 are oppositely disposed whereby to facilitate the outflow of the air through the exhaust 12.

in dotted lines in Fig. 2 the forward shutters are indicated at the opposite angle to the full line positions whereby the shutters will be effective in preventing the entrance of rain While at the same time affording ventilation. 'lhe dotted line positions of the rear shutters 14: correspond with the full line positions ofthe forward shutters 13 and when both the series of shutters 13, 14: are adjusted to correspond with the full line positions of the shutters l3 air-Will be taken the same plane, thereby completely closing the openings as might treme cold Weather.

The numeral 15 indicates the pivots of the various shutters, there being upper and lower pivots passing'through rearwardly xtending flanges 17, 17 on the shutter at be desi'rab e in enthe top and bottom, the flanges 1? receiving the pivots 18 while the larger flanges 17 are adapted for connecfion with operating means. The flanges 17 are in practice preferably disposed on the lower ends of the shutters 13 While the said flanges 1'? pertaining to the shutters 1e are formed on. the upper ends of the latter as Will be clear from comparison of Figs. 2 and 3 With Figs. 4 and The pivots 16 extend through in wardly projecting flanges 15 formed on the side of the hood 10 at the top and bottom of the openings 11, 12.

In order to actuate the shutters 13 in the illustrated example, an elongated operating rod or bar 18 is disposed at the inside of the opening 11 and pivoted as at 19 to the flange 17" of each of said shutters 18 The said. operating rod 18 connecting the seve 'al shutters 13 is pivotally secured. to one end of a link 20, the opposite end of link being pivoted as at 2,1 to an actuating slide on the hood 10 at the inner side thereof. in operating knob is provided on the slide 22, the shank 24 of the said knob extending through an opening in the hood and be ing threaded into the slide so that the turning of the knob may be utilized if desired to lock the shutters in a given adjustment. Similarly, an operating rod or'bar 18 is dis posed adjacent to the upper ends of the shut ters is and pivoted as at 19 to the flanges 17 of said shutters. A link 20 is pivoted at one end to the rod 18 and at its opposite end as at 21 to the slide 222 corresponding with the slide and having an operating lrnob 23 extending through and slidable in a slot 25 in the hood.

That portion of the hood 10, it will be observed, between the inlet opening 11 and the exhaust opening 12, presents a closed panel giving the necessary strength to the hood notwithstanding the provision of the inlet and exhaust shutters and aids in causing the air taken in at the front opening to be conducted adjacent to the motor parts before being exhausted.

With the above described hood an eilicient ventilation or cooling effect is produced to suit the varying weather conditions and the various adjustments to regulate the air current can be effected with facility and despatch.

I Wish to state in conclusion that although the illustrated example constitutes a practi cal embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied Without d'eparture from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new, and desire to secure by Leo ters Patent:

1.. A motor hood having in a side thereof a main inlet opening and a second exhaust opening rearward of the first opening, a se ries of shutters pivoted to the hood at each of said openings to turn about verticalaae and means to variously adiust the angular positions of the respective shutters to cause the forward series of said shutters to talre in air and the rear series at the opposite angle to the front shutters to exhaust said air, both series of shutters being movable from said intake and exhaust positions, to form closures of the respective openings, or to dis pose the front shutters at an angle to deflect rain While permitting ventilation, the rear shutters furthermore being movable to re verse tlieir angular positions to correspond with the air-intake adjustment of the front shutters for'taking air into both openings and causing it to pass through the rear of the hood for conducting off the radiated heat from parts in the rear of the hood.

2. A motor hood having in aside thereof intake and exhaust openings, the one forward of the other, a series of shutters pivotally mounted each of said openings to turn about vertical axes, and. actuating means for the respective series of shutters, the respective series of shutters being movable to corresponding angular positions or to reverse angular positions.

3. A. motor hood having ina side thereof intake and exhaust openings, the one forward of the other, the hood between said openings being in the form of a closed vertical panel, a series of shutters pivotally mounted at each of said openings to turn about vertical axes, and actuating means for the respective series of shutters, the respective series of shutters being movable to corresponding" angular positions or to reverse angular positions.

4. A motor hood having openings in a side thereof, one forward of the other, upper and lower flanges on said hood at the top and bottom of the respective openings, a seof emitters in each opening, the shutters being formed with flanges at the top and bottom, said shutter flanges being pivoted to the first mentioned flanges by vertical pivots, and actuating means for the shutters, the said shutters being movable to positions in a common plane with one another and with the side of the hood or to either of opposite angular positions.

5. A motor hood having an air inlet opening at a side thereof, a series of shutters pivoted in said opening, and actuating means for said shutters and adapted to move the same to either of reverse positions or to an intermediate position to close the opcnin n JGHN SAMUEL MALLORY.
